I need GCC for some Ruby gems. And I need LLVM as well for iOS development using Xcode 4.4. I already have LLVM installed through Xcode.
How can I install GCC in Mountain Lion without affecting any of LLVM binaries?
The fact is that because you have Xcode you already have GCC installed on your system. If you're trying to run GCC from the terminal and getting "command not found" then the reason is, starting with OS X 10.8 (Mountain Lion), the GCC "command line tools" are not installed by default with Xcode. The install procedure depends on your version of OS X and Xcode:
Installing the GCC command line tools in OS X 10.8 (Xcode 4.4):
Xcode -> Preferences -> Download -> Components -> Command Line Tools -> install
Installing the GCC command line tools in OS X 10.9 (Xcode 5.02):
I have not tried these instructions myself, but I'll move them here if someone tries them and they work:
http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/
Had the same issue after upgrading to Mountain Lion.
My fix, I found make and gcc etc in /Developer/usr/bin.
setenv PATH $PATH":/Developer/usr/bin"
Puts them back in the path.
Oh yeah, I was on Xcode 3.x.
Install macports and run:
$ sudo port install gcc
from the command line. There are about 20 different versions of gcc available as Macports.
I had Homebrew. So I did this.
brew install --enable-all-languages https://raw.github.com/Homebrew/homebrew-dupes/master/gcc.rb
It worked!
The easiest way to install anything on a Mac is by using Homebrew. There is a package for this very purpose:
brew tap homebrew/dupes
brew install apple-gcc42

I have currently switched to mac from linux and am missing xcowsay
xcoway requires X, for linux that is x11 for mac you will ned toinstall Xquartz.
According to http://www.doof.me.uk/2008/03/04/xcowsay-on-os-x/, xcowsay is suported in mac since 2008.
Download and install XQuartz from https://www.xquartz.org/. Then download and compile xcowsay from https://github.com/nickg/xcowsay/
I had to install XQuartz on Mac OS X and build from source.
I used homebrew to install the dependencies and cloned from the source at https://github.com/nickg/xcowsay/. I ran into an issue with autoreconf finding the autopoint command from gettext. Adding the gettext bin folder to my path solved it.
See steps below
brew install autoconf gettext gdk-pixbuf gtk+
export PATH="/usr/local/opt/gettext/bin:$PATH"
./configure
make
make install
You should look at Homebrew for OSX.
cowsay is available via the homebrew package manager. I do not see the X-Server version of cowsay.

I thought was a problem due to my old XCode, so I uninstalled it and then loaded GCC-10.6.pkg but the error was the same.
I thought that also osx-gcc could be outdate so I managed to find a XCode 4.2 and I installed it, but the error doesn't change
I found out that there is no "Command Line Tools for Xcode" for osX 10.6.8 so now I'm out of options.
There is a newer version of XCode (4.3.2) that is compatible with 10.6.8 but I wasn't able to get it, and sincerely, now I don't think that that could be the problem.
So, now, I'm out of options.
I can't upgrade to Lion, because my laptop doesn't support it.
The sad thing is that yesterday I decided to format my hd and reinstall OsX just to have a new, fresh, clean installation of homebrew!!!!!
Please.....help!!!!
I've just found out, that my homebrew doesn't work anymore after I upgraded to OS X Lion.
$ brew install clojure
Warning: Xcode is not installed! Builds may fail!
Error: No such file or directory - /usr/bin/cc
and
$ brew doctor
We couldn't detect gcc 4.2.x. Some formulae require this compiler.
We couldn't detect gcc 4.0.x. Some formulae require this compiler.
You have no /usr/bin/cc. This will cause numerous build issues. Please
reinstall Xcode.
Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
after some googling, I found out that I should upgrade Xcode to version 4.1. The problem is, I have version 3.2.5 installed and I can't find any way of uninstalling it.
When I look at App Store, it looks like I don't have Xcode installed at all. I'm afraid that if I install it via App Store, it will somehow conflict with the version I have currently installed. However I can't find it in Applications, and I can't find any update function either.
Software Update doesn't prompt me to update Xcode, and I also don't see it in Installed Software.
What should I do?
Thanks to the readme found at /Developer, I found a way to uninstall Xcode via
$ sudo /Developer/Library/uninstall-devtools --mode=all
edit: I just ran the installer for Xcode 4, and it detected old version of Xcode, offering me to move it to /Developer-old.
I fixed it by
In theory this should work if you have Xcode4.3 installed (in /Applications):
$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer/
Hi I just recently downloaded the most recent snow leopard update. Then I tried to plot something using Octave which has been installed on my computer for months (and plotting has worked all that time) Even since I installed the update, and I try to plot using octave I get the following error:

error: you must have gnuplot installed to display graphics; if you have gnuplot installed in a non-standard location, see the 'gnuplot_binary' function
I'm really not sure what to do. I'm way out of my league here.
The "note for MacOSX users" is no longer on the Octave homepage, and the workaround described in Marco's post didn't work for me either, but this did:
Open /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot in a text
editor. Use the editor search-and-replace feature to replace
"DYLD_LIBRARY_PATH" with "DYLD_FALLBACK_LIBRARY_PATH". There are four
instances that need to be replaced.
This is from the readme for the Octave MacOSX Binary. Note that it says it's for Lion users, but I'm running 10.6.8 and it worked for me.
I've recently build Octave and GNUplot on Lion using homebrew. Seems to work well. Here are some notes
Install Xcode from AppStore and HomeBrew (see Link)
Run 'brew install octave" and wait until graphicsmagick fails to compile
Run the command "brew install --use-clang --HEAD graphicsmagick". You might be asked to install Mercurial, just follow the instructions. You may also be asked to install fortran, so "brew install gfortran"
Run the command "brew install octave" again
Install Aquaterm
Now run "brew install gnuplot"
You now have the latest Octave installed. Just type octave from the terminal
To test the install run the following commands at the Octave command prompt
setenv("GNUTERM", "x11");
x = linspace(-10, 10, 100);
y = sin(x);
plot(x,y);
See the note for users of Mac OS X 10.6 on http://octave.sourceforge.net/. The changes solve the problem also in 10.5.8.
We updated freetype in OSX 10.6.5 and fontconfig, which links against freetype, wants this newer version. Gnuplot is failing to load because their developers are setting DYLD_LIBRARY_PATH which is forcing our libfontconfig to try using their libfreetype, which it cant.
This is a bug in Gnuplot.app ... developers should NEVER be setting DYLD_LIBRARY_PATH in shipping products!
I had the same problem and took me a while to find the "note for users of Mac OS X 10.6". I copy them here:
NOTES FOR SNOW LEOPARD USERS
1 - mkoctfile
Since OSX 10.6 the Apple shipped version of gcc builds by default 64bit binaries
As the libraries included with Octave.app version 3.2.3 are 32bit, you need to apply
the following patch in order for mkoctfile to work:
1.1) open the folder /Applications in the finder
1.2) right-click on Octave.app and select "show package contents"
1.3) navigate to /Applications/Octave.app/Contents/Resources/bin
1.4) right-click on the file "mkoctfile" and select "Open with -> Other ... -> TextEdit.app"
1.5) right after the line:
# along with this program; If not, see <http://www.gnu.org/licenses/>.
add the lines
CFLAGS="-m32 ${CFLAGS}"
FFLAGS="-m32 ${FFLAGS}"
CPPFLAGS="-m32 ${CPPFLAGS}"
CXXFLAGS="-m32 ${CXXFLAGS}"
LDFLAGS="-m32 ${LDFLAGS}"
and save.
2 - Gnuplot.app
An update to system libraries introduced with OSX 10.6.5 has broken the functionality
of the Gnuplot.app included with the Octave.app distribution, in order to use Gnuplot.app
on OSX 10.6.5 and later, you can use the fix described below:
2.1) open the folder /Applications in the finder
2.2) right-click on Gnuplot.app and select "show package contents"
2.3) navigate to /Applications/Gnuplot.app/Contents/Resources/bin
2.4) right-click on the file "gnuplot" and select "Open with -> Other ... -> TextEdit.app"
2.5) change the line:
DYLD_LIBRARY_PATH="${ROOT}/lib:${DYLD_LIBRARY_PATH}"
to
DYLD_LIBRARY_PATH="${ROOT}/lib"
and save.
NOTES FOR LEOPARD USERS
An update to system libraries introduced with OSX 10.5.8 has broken the functionality
of the Gnuplot.app included with the Octave.app distribution, in order to use Gnuplot.app
on OSX 10.5.8 and later, you can use the same fix described above for OSX 10.6.5.
I tried the above and it did not help. The source of the problem seems to be the version of gnuplot that comes with the Octave.app install.
I installed gnuplot directly with 'brew' and then I removed gnuplot from my Applications folder. Once that change was made, Octave was able to find the newer version of gnuplot that was compiled with the correct dependencies.
If you don't mind using MacPorts, you can install octave by the following command. And it will be a 64-bit version.
sudo port install octave-devel
I just want to share my experience regarding this issue.
I had similar problem today when I tried to use Octave/Gnuplot in Mac OS X (10.7.5, Lion) and none of the solutions above worked for me.
However I found another solution that did work, which is described in https://github.com/jyr/MNPP/issues/28. Basically, I did the following:
sudo cp /usr/X11/lib/libfreetype.* /Applications/Gnuplot.app/Contents/Resources/lib
Mountain Lions can also install Octave 3.4.0 with the dmg and throw in the older 4.2 gnuplot instead from the Maxima dmg. Easiest, but not the most recent version. (A classmate's idea which worked.)
Replacing the 4 instances of "DYLD_LIBRARY_PATH" with "DYLD_FALLBACK_LIBRARY_PATH" did not work for me on Mac OS X 10.9.
However, the second option given here:
http://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/2011-04-21%20binary%20of%20Octave%203.4.0/
did work. i.e. using Gnuplot-4.2.6 that is bundled with Maxima DMG. Link below. http://sourceforge.net/projects/maxima/files/Maxima-MacOS/5.26.0-MacOSX/
I just copied Gnuplot.app into /Applications.
I have installed the developer tools. I can compile code via Xcode and according to the docs /usr/bin/gcc & /usr/bin/cc should point to /usr/bin/gcc-4.0. Neither the symlinks or gcc-4.0 exist on my system (Snow Leopard). All I wish to do is compile some C on the terminal! I'm amazed by how complicated this task is. The command GCC is unsurprisingly returning "gcc: command not found".
Can anyone shed some light on this?
No! Reinstalling is the wrong answer!
Newer versions of XCode require you to install the command-line versions of the tools separately. In XCode, go to Preferences | Downloads, check the Components tab, and install them from there:
These binaries should be there after installing xcode. Check your path settings, and if you still don't have these reinstall xcode
Command line tools are no longer included with the latest XCode (even as an add on). Now you can download them here:
https://developer.apple.com/downloads/index.action
Did you install the latest Xcode after installing Snow Leopard, or is this the version of Xcode from a previous OS installation?
On my system with a clean Snow Leopard install the default compiler (and the one symlinked from cc and gcc) is gcc-4.2
I do have gcc-4.0 too, although it's not the default.
